How Mimecast secure email options work.

To send a message with secure email options, users create a new message in Outlook or Mimecast for Mac as usual and then choose the Send Secure option on the Mimecast tab. Before sending the message, users can choose from several secure email options to require read receipts, set message expiration dates, or prevent the recipient from printing, replying or replying all to the message.

After the message is sent, the email and any attachments are uploaded to the Mimecast cloud, scanned for malware and checked against policies concerning content control and data leak prevention. Emails and attachments are then stored in Mimecast's secure AES encrypted archive.

Message recipients then receive a notice with information about how to log onto Mimecast's secure web portal. Once logged on, recipients can retrieve messages, download attachments and send emails and documents back to the original sender.

Mimecast also provides administrators with secure email options that automatically initiate a secure message when an email meets certain policy criteria. For example, emails sent to a particular domain or to a specific recipient may be automatically sent via Secure Messaging, as well as email that contains certain keywords like "confidential" in the subject line.

Benefits of Mimecast's secure email options.

Mimecast's secure email options enable you to:

Simplify encryption by providing users with an easy way to send secure messages and attachments without needing knowledge of encryption keys or certificate management, and without requiring recipients to download and install software.
